Abstract
A magnetic powder dispensing structure for tablet printing comprises a powder collecting device, a printing device, a guide rod device and a printing platform, the powder collecting device comprises a powder collecting box, a powder feeding device, a plurality of stirring rods, a plurality of rocker arms, a pressing rod, a driving motor and a first electromagnetic attraction device; the printing device comprises a second electromagnetic attraction device. The printing device and the powder collecting device are capable of moving laterally through the guide rod device, and capable of being magnetically attracted with each other or detached from each other by energizing or de-energizing the first electromagnetic attraction device and the second electromagnetic attraction device, thereby the powder collecting device can be driven when dispensing powder, and the printing device is capable of operating independently during printing.
